Assembling the mast

Mast, view from above (compass module) The mast is carrying the LED assembly (white light to the back and sides, blue light for the effect) and the electronic compass. I started with cutting a aluminum tube into shape (slanted cuts at both ends so the mast can be mounted at angle while the platform on top stays horizontal).

Mast, view from below (LED assembly) The LED board and the compass got mounted on a small circular plywould disk with some wire. The disk I glued onto the top of the mast.

Next was the cabling: a nine wire cable (from a serial cable) was pulled through the tube, and soldered to the LED assembly and the compass module. The other end is connected to the Basic Stamp (4 wires for the compass) and power drivers connected to the stamp outputs (one wire for the 12V lighting power supply, and 2 wires for the white and blue LED ground connection).
